摘要： 为延长东海某油气田的经济寿命，依托其现有的设施，选择已有井槽侧钻一口大位移井，以开发该油气田西南部的中山亭构造的储层。通过优化套管打捞技术，成功完成大尺寸长距离套管打捞作业，为后续侧钻超深大位移井创造了条件。通过优化油基钻井液体系、摩阻扭矩控制、井眼净化、当量循环密度（ECD）控制和下套管固井等钻井关键技术，顺利完成了东海首口超深大位移井钻井作业。

Abstract: To prolong the economic life of an oil and gas field in the East China Sea, it was considered to drill an extended reach well through existing well, relying on the existing facilities. In this way, we could develop the reservoir of the midmountain pavilion in the southwest of the oil and gas field. By optimizing the casing fishing technology, successful completion of large-size long-distance casing fishing operation was successfully implemented, which laid the foundation of the subsequent lateral drilling of the ultra-deep extended reach well. With the further optimization of technologies including oil-based drilling fluid system, friction and torque control, hole cleaning, equivalent circulation density (ECD) control, and casing cementing, the drilling operation of the first ultra-deep extended reach well in the East China Sea was successfully completed.
